1. What is 'perseveration' shown in patients with DLPFC damage?
- Cant create rules which generalise across contexts. e.g in Wisconsin card task will always use previously learned rule for sorting
- Only create generalised rules which are not applied to behaviour, e.g on Wisconsin card task will show random behaviour with a seemingly different rule each time
- Continue to use previously learned rules not from an inability to switch. e.g in Wisconsin card task will always use previously learned rule for sorting
- Use a new rule on each trial reflecting an inability to learn. Not from an inability to switch e.g on Wisconsin card task will show random behaviour with a seemingly different rule each time
